Colony Collapse Disorder The colony collapse disorder of honeybees has become a very problematic issue. The Natural Resources Defense Council states that nearly that nearly one-third of all honeybee colonies in the country have vanished, putting many fruits and vegetables at risk. A controversial type of pesticide called neonicotinoids has become a prime suspect in this phenomenon, as it affects bees’ sense of direction and making it hard for them to find home. In order to prevent this disaster from continuously occurring, neonicotinoids should be banned or used more sparingly and replaced with an alternative type of pesticide. Author Brandon Keim, author of article “Controversial Pesticide Linked to Bee Collapse” states neonicotinoids began to be used in the mid-1990s as less-toxic alternatives to human-damaging pesticides.
Geography 101 13 July 2013 The Deforestation of the Amazon The deforestation of the Amazon is going to have catastrophic consequences. The legal and illegal results of chopping down trees in this great wetland, has dire consequences that our generation may not suffer but future generations will. “The Amazon is a vast region that spans across eight rapidly developing countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname and French Guiana, an overseas territory of France. The landscape contains: one in ten known species on Earth; 1.4 billion acres of dense forests, half of the planet's remaining tropical forests; 4,100 miles of winding rivers, 2.6 million square miles in the Amazon basin, about 40 percent of South America” (“Amazon”). So you ask, why does it matter if we chop down a few trees?
Bush Honeysuckles Bush Honeysuckles are inavasive species plants that grow quickly and agressivly diplacing other Plants. Bush Honeysuckles are harmful to plants, mammals, and wildlife. Of the roughly 2,300 inavasive plant species in Indiana, 25% are non native and are responsible for degrading and destroying thousands of acres of our natural plant communities of Indiana. Bush Honeysuckles where introduced to Northern America in late 1800s and 1900s. They are now reported to be found in 81 counties in Indiana.
Most disturbing are the attacks on very young Lodgepole Pine as a lot of this volume has actually been reforested from previous cutting and contributes to the province’s sustained cut (AAC). The AAC is now threatened not only from losing mature volumes but also losing the successive regeneration that we have come to rely on for the future. On their own, the beetles can fly 1 or 2 kilometers (kms), but with the right wind currents can fly more than 100 kms, which explains their ability to cross the Rocky Mountains into Alberta. This is significant in terms of threat as it now becomes a National concern with the MPB has adapting to attacking the Jack pine forests that cover areas of Alberta, Saskatchewan, Manitoba, Ontario and
Since the time when the “Plague” caused so much death in Europe the human race has accumulated a vast volume of knowledge that would have been unthinkable as recent as a century ago. President John F. Kennedy in his inaugural address on January 20, 1961 said: “The world is a very different one now, for man holds in his mortal hands the power to abolish all forms of human poverty, and all forms of human life” (Kennedy par. 4). With the advances that have been made in science it is plausible that a disease could be genetically engineered and if introduced either accidently or intentionally into the populace could have a devastating effect on
The largest tropical rainforest in the world, the Amazon, is being rapidly destroyed. The reasons are many, and little is being done to prevent this. The use of chemical defoliants and the attempt of building a road through the Amazon has done horrific damage to the rainforest. Logging is a part of the reckless destruction of the beautiful rainforest. Cattle ranching contributes greatly to the demise of the amazonian rainforest.
Geographic and Environmental Factors There are many reasons that people migrate to other locations. Sometimes it is due to weather, famine, war or violence, and fear of persecution to name a few. This is a discussion of two situations that lead to the expansion of the United States, the development and expansion of Egypt and the diffusion of potatoes from an early society to modern day use. Environmental or Physical Geographic Factors Irish Potato Famine In the mid-1800s The Irish potato famine lasted for six years and led to the death of over one million people and caused an additional one million people to leave Ireland. Ireland was among one of the poorest nations in the world during this time, the residents relied heavily on eating potatoes on a daily basis.
Introduction: Soil inhabiting microbes play chief role in damaging juvenile plants under nursery. Pre-emergence or post-emergence nature of damage may leads to complete damage. However, many serious diseases are associated with soil-borne plant pathogens, which results in damping off, root rot, crown rot and wilts in various field and horticultural crops especially in nursery stage. Soil borne diseases are a common problem in nursery production which leads to sustainable economic loss by attacking the juvenile plants at early stage of life. Practical application of this knowledge will lead to healthier plants and improved plant growth with greater uniformity.
With the depletion of the forest that converts the carbon dioxide into oxygen it has monumental negative effects on the planet as a whole. “Eleven developing countries recently linked to 82 percent of the carbon dioxide buildup due to deforestation will likely come under the greatest pressure for change: Brazil, Indonesia, Colombia, Cote D’Ivoire, Thailand, Laos, Nigeria, Vietnam, Philippines, Myanmar (Formally Burma) and India”. (“cooper”) One of the major locations deforestation is in the south Asian country Thailand. “Located wholly within the tropics, Thailand encompasses diverse ecosystem, including the hilly forested areas of the northern frontier, the fertile rice fields of the central plains, the broad plateau of the northeast, and the rugged coast along the narrow peninsula.”(“Thailand”). Since the formation of the country Thailand
There are many problems that the rainforest biome encounters. One of the biggest problems is the amount of trees being cut down; millions a year are being cut down. On average, in each hour of the day 1,000 to 3,000 acres of the rainforest are destroyed. Meaning 50,000,000 acres each calendar year are being destroyed. Another problem that the rainforests encounter is the medical side.
